This helper was wrong and could indicate that a valid\npointer returned to userspace was a failed syscall. The fix is to fix the\nlayering foolishness. We now pass audit_syscall_exit a struct pt_reg and it\nin turns calls back into arch code to collect the return value and to\ndetermine if the syscall was a success or failure. We also define a generic\nis_syscall_success() macro which determines success/failure based on if the\nvalue is \u003c -MAX_ERRNO. This works for arches like x86 which do not use a\nseparate mechanism to indicate syscall failure.\n\nWe make both the is_syscall_success() and regs_return_value() static inlines\ninstead of macros. The reason is because the audit function must take a void*\nfor the regs. (uml calls theirs struct uml_pt_regs instead of just struct\npt_regs so audit_syscall_exit can\u0027t take a struct pt_regs). Since the audit\nfunction takes a void* we need to use static inlines to cast it back to the\narch correct structure to dereference it.\n\nThe other major change is that on some arches, like ia64, MIPS and ppc, we\nchange regs_return_value() to give us the negative value on syscall failure.\nTHE only other user of this macro, kretprobe_example.c, won\u0027t notice and it\nmakes the value signed consistently for the audit functions across all archs.\n\nIn arch/sh/kernel/ptrace_64.c I see that we were using regs[9] in the old\naudit code as the return value. But the ptrace_64.h code defined the macro\nregs_return_value() as regs[3]. I have no idea which one is correct, but this\npatch now uses the regs_return_value() function, so it now uses regs[3].\n\nFor powerpc we previously used regs-\u003eresult but now use the\nregs_return_value() function which uses regs-\u003egprs[3]. regs-\u003egprs[3] is\nalways positive so the regs_return_value(), much like ia64 makes it negative\nbefore calling the audit code when appropriate.\n\nSigned-off-by: Eric Paris \u003ceparis@redhat.com\u003e\nAcked-by: H.

When a daemon set oom_score_adj\nand make children, it\u0027s hard to know where the value is set.\n\nThis patch adds some tracepoints useful for debugging. This patch adds\n3 trace points.\n - creating new task\n - renaming a task (exec)\n - set oom_score_adj\n\nTo debug, users need to enable some trace pointer. Maybe filtering is useful as\n\n# EVENT\u003d/sys/kernel/debug/tracing/events/task/\n# echo \"oom_score_adj !\u003d 0\" \u003e $EVENT/task_newtask/filter\n# echo \"oom_score_adj !\u003d 0\" \u003e $EVENT/task_rename/filter\n# echo 1 \u003e $EVENT/enable\n# EVENT\u003d/sys/kernel/debug/tracing/events/oom/\n# echo 1 \u003e $EVENT/enable\n\noutput will be like this.\n# grep oom /sys/kernel/debug/tracing/trace\nbash-7699 [007] d..3 5140.744510: oom_score_adj_update: pid\u003d7699 comm\u003dbash oom_score_adj\u003d-1000\nbash-7699 [007] ...1 5151.818022: task_newtask: pid\u003d7729 comm\u003dbash clone_flags\u003d1200011 oom_score_adj\u003d-1000\nls-7729 [003] ...2 5151.818504: task_rename: pid\u003d7729 oldcomm\u003dbash newcomm\u003dls oom_score_adj\u003d-1000\nbash-7699 [002] ...1 5175.701468: task_newtask: pid\u003d7730 comm\u003dbash clone_flags\u003d1200011 oom_score_adj\u003d-1000\ngrep-7730 [007] ...2 5175.701993: task_rename: pid\u003d7730 oldcomm\u003dbash newcomm\u003dgrep oom_score_adj\u003d-1000\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c6968e73b90c2a2fb9a32d4bad249f8f70f70125", "tree": "67ec90fc8e187fcf316298dd9d514bbbbbc8f187", "parents": [ "c0a32fc5a2e470d0b02597b23ad79a317735253e" ], "author": { "name": "Stanislaw Gruszka", "email": "sgruszka@redhat.com", "time": "Tue Jan 10 15:07:31 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 10 16:30:42 2012 -0800" }, "message": "PM/Hibernate: do not count debug pages as savable\n\nWhen debugging with CONFIG_DEBUG_PAGEALLOC and debug_guardpage_minorder \u003e\n0, we have lot of free pages that are not marked so.
